SF-36: Short Form 36 (SF-36). was considered statistically significant. Groups showed no significant differences at the baseline. Groups showed significant differences in all outcomes after two years. There was a significant difference in improvement over time between groups in all outcomes except for the SF-36 mental component summary (MCS).
